Biggest Fashion Faux Pas

Wearing a backless dress is one thing but airing out your derrière is another! This fashion faux pas is definitely a backless blunder. (Photo by Stephen Shugerman/Getty Images)

Pattern Explosion

Don’t try to mix and match prints or you’ll look way too busy! Topping off a patterned fuchsia dress with a sequined purple cape is not going to get you on the “Best Dressed” list. (credit: Stephen Shugerman/Getty Images)

Way Too Much Cleavage

There’s nothing wrong with showing off your best *ahem* assets, but it’s important to do so in moderation. Jodie Marsh, perhaps something a little more conservative would have been appropriate for a red carpet movie premiere. (credit: Dave Hogan/Getty Images)

Underwear As Outerwear

There is a fine line between “sexy” and “shameful.” Wearing underwear as outerwear is never a stylish fashion statement. (credit: Jo Hale/Getty Images)

Too Tight

I’m trying to figure out how Team Scarlett managed to find a dress that’s too small and too big? Her breasts are clearly getting strangled by the straps, and the extra fabric is not complimenting her fabulous frame. When in doubt, size up!(credit: Gareth Cattermole/Getty Images)

VPL (Visible Panty Lines)

It’s not enough that your bra strap hangs out, but women should never make the mistake of VPL! If your panties are shifting in any way, the whole world will know. (credit: Hogan/Getty Images)

Granny Fanny Pack

There is absolutely no reason you should EVER wear a fanny pack. I don’t care if you’re a tourist, a dog walker or Donna Karen. (credit: Astrid Stawiarz/Getty Images)

Walking Political Billboard

It’s one thing to be patriotic, but wearing your vote will always be a fashion faux pas! Barack Obama is not a souvenir… he’s The President. (credit: Jason Merritt/Getty Images)

Funky Fake Nails

Even superstars like Beyonce choose to decorate their fake nails with funky designs. Your nails can take you from “classy” to “trashy” in a snap. (credit: Jason Merritt/Getty Images)

Unflattering Unitard

Rihanna is known for her edgy style, but this 80′s unitard nightmare is unflattering and ugly. (credit: Bryan Bedder/Getty Images)

Mullet Madness

Business in the front… party in the back! It’s amazing that, even after 25-30 years, some people still don’t realize that mullets are not in style anymore… and they were never cool. (credit: Frederick M. Brown/Getty Images)

Terrible Tutu

Talk about tacky! Bai Ling often rocks the red carpet in risqué styles, but wearing a tutu with a fur stole is a clear fashion faux pas. Even though Carrie Bradshaw wore a tutu in the opening credits of “Sex and the City,” that doesn’t mean it’s chic. (credit: Krafft Angerer/Getty Images)

Mesh Muscle Shirt

Men, no one wants to see your nipples on the red carpet. Mesh muscle shirts will never be in style. (credit: Stuart Wilson/Getty Images)

Trashy Tights

Oh Ke$ha, no one does filthy hot mess quite like you do! And while you have to admire her creativity, her destroyed tights look more “garbage” than “glam.” (credit: Valerie Macon/Getty Images)

Animal Print Overload

Animal print may be a hot trend for fall, but Paloma Faith went WAY too far. Plus, adding a hat-box purse and a red flower bouquet on her head clearly didn’t accent the print. (credit: Gareth Cattermole/Getty Images)

Too Tan

The “Jersey Shore” crew isn’t shy about their love of tanning but Nicole “Snooki” Polizzi takes it to a whole new level! She is way too tan and could easily double as an umpa lumpa.(Photo by Kevin Winter/Getty Images for VH1)
